Question 6 of 433

Scenario -

You have been asked to evaluate an OSPF network setup in a test lab and to answer questions a customer has about its operation. The customer has disabled your access to the show running-config command.

Instructions -

- Enter IOS commands on the device to verify network operation and answer for multiple-choice questions.

- THIS TASK DOES NOT REQUIRE DEVICE CONFIGURATION.

- Click on the icon or the lab at the bottom of the screen to gain access to the console for each device.

- No console or enable passwords are required.

- To access the multiple-choice questions, click on the numbered boxes on the left of the top panel.

- There are four multiple-choice questions with this task. Be sure to answer all four questions before selecting the Next button.

Question 7 of 433

A network engineer executes the show crypto ipsec sa command. Which three pieces of information are displayed in the output? (Choose three.)

    Correct Answer:

    The 'show crypto ipsec sa' command provides detailed information about IPsec Security Associations (SAs). The output includes details such as the inbound and outbound crypto map details, the remaining key lifetime for the SA, and other metrics related to packet handling and encryption. Specifically, the remaining key lifetime (to monitor how much time or data is left before the encryption key needs to be renegotiated) is crucial. Another important piece of information is the path Maximum Transmission Unit (MTU), which shows the largest packet size that can be transmitted over the network path without needing to be fragmented. Thus, the three pieces of information displayed in the output are the inbound crypto map, the remaining key lifetime, and the path MTU.

Question 8 of 433

Refer to the following output:

Router#show ip nhrp detail -

10.1.1.2/8 via 10.2.1.2, Tunnel1 created 00:00:12, expire 01:59:47

TypE. Dynamic, Flags: authoritative unique nat registered used

NBMA address: 10.12.1.2 -

What does the authoritative flag mean in regards to the NHRP information?

    Correct Answer: A

    The authoritative flag in NHRP information indicates that the NHRP information was obtained directly from the Next Hop Server (NHS), which is responsible for maintaining the NBMA-to-IP address mapping for a particular destination. This means that the information is reliable and provided by an authoritative source within the NHRP protocol.

Question 9 of 433

Which encapsulation supports an interface that is configured for an EVN trunk?

    Correct Answer:

    The encapsulation that supports an interface configured for an EVN trunk is 802.1Q. EVN (Easy Virtual Network) trunks are allowed on interfaces that support 802.1Q encapsulation. This is specifically mentioned in the provided restrictions for EVN.

Question 10 of 433

Which three characteristics are shared by subinterfaces and associated EVNs? (Choose three.)

    Correct Answer: A, B, C

    All three characteristics of subinterfaces and associated EVNs mentioned in the correct options include IP address, routing table, and forwarding table. These elements are crucial for the operation of subinterfaces within Enhanced Virtual Networking (EVN). Each EVN is capable of supporting overlapping IP addresses in different contexts due to unique routing and forwarding tables assigned to each EVN, allowing efficient data management and network traffic handling. These characteristics ensure that multiple Virtual Networks can coexist and operate on the same infrastructure without interfering with each other.
